During the process, the support roller drives the shaft to rotate under the action of the wire.

At this time, the pushing roller drives the wire to deviate to one side, so that the wire is distributed in a wave shape under the action of the first pushing mechanism, the tensioning mechanism and the support roller, so as to facilitate the tensioning of the wire and prevent a large number of wires from bending and entangled together to interfere with the later maintenance of the distribution box.

[0017] The present invention provides a tensioning mechanism and a second pushing mechanism. When the wire is bundled by the wire bundling mechanism, one end of the wire will act on the rotating roller. As the wire continues to move, the swing plate will deflect to one side under the pull of the wire, and the swing plate will push the pushing plate to slide to one side when deflecting. The pushing plate will drive one end of the balance plate to deflect to one side when sliding, and the other end of the balance plate will deflect in the opposite direction. At this time, the other end of the balance plate will push the push rod to move to one side when deflecting in the opposite direction, thereby pushing the squeezing roller to slide to one side through the push rod, so that the wire is squeezed by the squeezing roller. The cooperation between the tensioning mechanism and the second pushing mechanism can effectively tighten the wiring of the wire, thereby improving the wiring effect of the wire and preventing two adjacent wires from being entangled together due to the long wire when wiring, thereby causing wear between the two wires.

A through opening 9 is provided between the wire openings 7, and a rotational connection is formed between two guide rollers 10 and the inner wall of the first wire opening 7 near the top through a bearing. An axle rod 19 is rotationally connected between the opposite sides of the first wire opening 7 through a bearing, and a support roller 11 is fixedly sleeved on the outer wall of the axle rod 19. A conductor 16 is arranged inside the wire harness mechanism 5, and a first pushing mechanism 17 is arranged on one side of the first wire harness opening 7 for facilitating the tightening of the conductor to prevent the conductor 16 from having a longer length during the wiring process due to the different distances between the components inside the distribution box, and there are many components that need to be wired inside the distribution box. Therefore, a large number of conductors 16 will be bent and entangled together, causing interference to the later maintenance of the distribution box.

[0029] On the basis of the above, two rotating rods 13 are rotatably connected between the inner walls on both sides of the opposite sides of the second wire harness opening 8 through bearings, and the positions of the two rotating rods 13 are staggered. The outer wall of one of the rotating rods 13 is fixedly sleeved with the first wire harness roller 14, and the outer wall of the other rotating rod 13 is fixedly sleeved with the second wire harness roller 15. The outer walls of the support roller 11, the first wire harness roller 14 and the second wire harness roller 15 are all provided with anti-slip grooves, which can increase the friction between the wire 16 and the first wire harness roller 15 and the second wire harness roller 14, so as to improve the tensioning effect of the wire 16 and prevent the wire 16 from slipping.

[0030] On the basis of the above, the first pushing mechanism 17 is composed of a pushing plate 24, an extension plate 26, a pushing roller 27 and a transmission assembly 28, and one end of the pushing plate 24 is connected to the inner wall of one side of the first wire bundle port 7 by bolts, and a pull-out port 25 is provided on one side of the pushing plate 24, and the extension plate 26 is slidably connected to the inner wall of the pull-out port 25. A fixing groove is provided at one end of the extension plate 26, and the opposite sides of the fixing groove are rotatably connected to the pushing roller 27 through bearings. Connection ports are provided on both sides of the bottom of the pull-out port 25, and the extension plate 26 is connected to the shaft rod 19 by a transmission assembly 28, which is convenient for tightening the wire 16 to prevent the wire 16 from being longer in length due to the different distances between the components inside the distribution box during the wiring process, and there are many components that need to be wired inside the distribution box. Therefore, a large number of wires 16 will be bent and entangled together, causing interference with the later maintenance of the distribution box.

[0031] On the basis of the above, the transmission assembly 28 is composed of a rotating shaft 29, two pulleys 31, a belt 32, a gear 33 and a rack 30, and a rotational connection is formed between the two pulleys 31 and the belt 32. The two pulleys 31 have different sizes, one of which is fixedly sleeved on the outer wall of the rotating shaft 29, and the other pulley 31 is fixedly sleeved on the outer wall of the shaft 19. The two ends of the rotating shaft 29 are rotatably connected to the two sides opposite to the first harness port 7 through bearings. The gear 33 is fixedly sleeved on the outer wall of the rotating shaft 29. The top of the rack 30 is connected to the bottom of the extension plate 26 by bolts, and the rack 30 is slidably connected to the connecting port. The gear 33 is meshed with the rack 30. When the wire 16 is wired, the support roller 11 drives the shaft 19 to rotate under the action of the wire 16. At this time, the shaft 29 drives the gear 33 to rotate through the cooperation between the two pulleys 31 and the belt 32, so that the gear 33 drives the rack 30 to move to one side through meshing, and then the extension plate 26 extends from the inside of the pull-out port 25. At this time, the pushing roller 27 drives the wire 16 to deviate to one side, so that the wire 16 is distributed in a wave shape under the action of the first pushing mechanism 17, the tensioning mechanism 12 and the support roller 11, so as to facilitate the tensioning of the wire 16.

[0032] On the basis of the above, a tensioning mechanism 12 is provided on the inner wall of the other side of the first wiring harness port 7, and the tensioning mechanism 12 includes a swing plate 20 and two first springs 21, one end of the swing plate 20 is connected to the inner wall of one side of the first wiring harness port 7 by a hinge, the swing plate 20 is tilted, and one side of the swing plate 20 and the inner wall of one side of the first wiring harness port 7 are fixedly connected with the two ends of the first spring 21, so that the wiring of the wire 16 can be tightened.

[0033] On the basis of the above, a slot 22 is formed at one end of the swing plate 20, and rollers 23 are rotatably connected between opposite sides of the slot 22 via bearings to reduce friction between the wire 16 and the swing plate 20 and prevent the surface of the wire 16 from being worn.

[0034] Example 2

[0035] Reference Figure 1-8 , a wiring device for a distribution box. Compared with Example 1, on the basis of Example 1, a second pushing mechanism 18 is provided on one side of the first wiring port 7, and the second pushing mechanism 18 is matched with the tensioning mechanism 12.

[0036] On the basis of the above, the second pushing mechanism 18 includes a support frame 34, a balance plate 35 and an extrusion roller 37, and the two ends of one side of the extrusion roller 37 are connected to the first cable port 7 by a second spring 38 through bolts, one side of the support frame 34 is connected to the cable seat 6 by bolts, and the support frame 34 and the balance plate 35 are rotatably connected by a bearing. Both ends of one side of the first cable port 7 are penetrated by a sliding opening, and the inner wall of one of the sliding openings is slidably connected to a push plate 36, and the two ends of the push plate 36 are respectively in contact with one side of the swing plate 20 and one end of the balance plate 35, and the inner wall of the other sliding opening is slidably connected to a push rod 39, and the two ends of the push rod 39 are respectively in contact with one side of the extrusion roller 37 and the other end of the balance plate 35. As the wire 16 continues to move, at this time, the swing plate 20 will deflect to one side under the pull of the wire 16, and the swing plate 20 will push the push plate 36 to slide to one side when deflecting, and the push plate 36 will drive one end of the balance plate 35 to deflect to one side when sliding, and the other end of the balance plate 35 will deflect in the opposite direction. At this time, the other end of the balance plate 35 will push the push rod 39 to move to one side when deflecting in the opposite direction, thereby pushing the squeezing roller 37 to slide to one side through the push rod 39, thereby squeezing the wire 16 through the squeezing roller 37, and the cooperation between the tensioning mechanism 12 and the second pushing mechanism 18 can effectively tighten the wiring of the wire 16, thereby improving the wiring effect of the wire 16.

[0037] In summary, with the help of the above technical solution of the present invention: when wiring the distribution box, the wire 16 is connected as shown in the attached Figure 2 and 3As shown, it is connected to the terminal 3 through the wire harness mechanism 5 and the wire threading hole 2. During this period, when the wire 16 passes through the wire harness mechanism 5, the connection of the wire 16 is guided by the guide roller 10. The wire 16 will be connected to the terminal 3 through the wire threading hole 2 under the action of the first pushing mechanism 17, the second pushing mechanism 18, the tensioning mechanism 12, the support roller 11, the first wire harness roller 14 and the second wire harness roller 15 in sequence. During this period, when the wire 16 is wired, the support roller 11 will drive the shaft 19 to rotate under the action of the wire 16. At this time, the rotating shaft 29 drives the gear 33 to rotate through the cooperation between the two pulleys 31 and the belt 32, so that the gear 33 drives the rack 30 to move to one side through meshing, thereby extending the extension plate 26 from the inside of the drawing port 25. At this time, the pushing roller 27 will drive the wire 16 to deviate to one side, so that the wire 16 is in the first pushing roller. Under the action of the mechanism 17, the tensioning mechanism 12 and the supporting roller 11, the distribution is in a wave shape, so as to facilitate the tensioning of the wire 16. One end of the wire 16 will act on the rotating roller 23. As the wire 16 continues to move, at this time, the swing plate 20 will deflect to one side under the pull of the wire 16, and the swing plate 20 will push the push plate 36 to slide to one side when deflecting, and the push plate 36 will drive one end of the balance plate 35 to deflect to one side when sliding, and the other end of the balance plate 35 will deflect in the opposite direction. At this time, the other end of the balance plate 35 will push the push rod 39 to move to one side when deflecting in the opposite direction, thereby pushing the squeezing roller 37 to slide to one side through the push rod 39, so that the wire 16 is squeezed by the squeezing roller 37. The cooperation between the tensioning mechanism 12 and the second pushing mechanism 18 can effectively tighten the wiring of the wire 16, thereby improving the wiring effect of the wire 16.

[0038] The wire connection process is completed manually, that is, the wire is manually inserted from the second wire bundle port into the wire threading hole, and the wire is manually connected to the terminal. Figure 1 It can be seen that the positions of the wire threading hole and the second wire bundle port correspond to each other and are independently arranged, thereby avoiding the phenomenon of multiple wires being entangled during wiring.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
